We just returned from a six day trip to Orlando--stayed at Bonnet Creek Resort, but didn't do WDW or other parks. We drove to the Clearwater Beach area one day and went to Caladesi Island on the Gulf. It was very nice, but probably not something we would do again. We had a very good meal in Dunedin, at Sea Sea Riders Restaurant. The traffic from Orlando to the Gulf was very heavy both going over and coming back, and took approx. 90+ minutes.
Another day we drove to Cocoa Beach, on the Atlantic, and enjoyed the beach for a few hours. Beach access was plentiful as the city has two or three public parks/parking areas that have restrooms, showers, etc. Traffic to Cocoa was much lighter and a quicker trip than the Gulf. We would definitely choose Cocoa over the Gulf side, for ease of getting there, beach access, etc. Cocoa Beach has a huge Ron Jon Surf Shop that had everything beach-related and decent prices too.
I used Tripadvisor to look at restaurants, things to do, etc. and found their ratings to be pretty reliable with what we saw and did. Let me know if you have any questions.
